Seeking proof in near-death claims

At 18 hospitals in the U.S. and U.K., researchers have suspended pictures, face up, from the ceilings in emergency-care areas. The reason: to test whether patients brought back to life after cardiac arrest can recall seeing the images during an out-of-body experience.

People who have these near-death experiences often describe leaving their bodies and watching themselves being resuscitated from above, but verifying such accounts is difficult. The images would be visible only to people who had done that.

"We've added these images as objective markers," says Sam Parnia, a critical-care physician and lead investigator of the study, which hopes to include 1,500 resuscitated patients.
